Instructions are fairly straightforward if limited, and the price is certainly reasonable. But attempts to accurately cut all the edge / corner tabs proved frustrating, and I began redesigning it on my own to have the pieces join in a different way. Unless you have the tools to make this out of some stout material (wood, plastic, etc), don't bother trying to cut it from thickened matt board or cardboard. It won't turn out soundly enough for assembly in the end. Foam board might work if you don't care about durability.
